zEvents is an open source (LGPL) JavaScript library designed to ease the creation of custom objects that support DOM-style events and event handlers. The classes contained within the zEvents library are not standalone; they are designed to be "abstract" classes that can be inherited from to provide event functionality.
zEventThe zEvent class is based on the DOM
Event interface and is used to provide contextual information about an event to the handler
processing the event. A subclass of zEvent is generally passed as the first parameter to an
event handler. More specific context information is passed to event handlers by deriving additional
subclasses from zEvent which contain information directly relating to the type of event
they accompany.
zEventTargetThe zEventTarget class is based on the DOM
EventTarget interface and is used to provide registration and removal of event listeners
on an object and to dispatch of events to that object. This class is not intended to be used by itself, but
rather as a superclass for objects needing to support events.
